HAIR-DRYING APPARATUS.

Specification of Letters Patent.

Patented Mar. 25, 1913.

Application led June 26, 1911. Serial No. 635,421.

To all whom it may concern.'

Be it known that I, AUGUST SGHAEFFER, a citizen of the German Empire, residing at 'Frankfort-on-the-Main, in the Province of Hesse-Nassau, and Empire of Germany,

of gravity of the apparatus, whereby the handling of the device is greatly simplied and the arm is not tired by the constant effort to balance the apparatus which would otherwise be necessary.A

The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being pointed out in the claims appended to the escri tion.

In t e drawings, Fi re '1 is a view,partly in section and partly 1n elevation, of a ventilating fan and motor embodying my invent-ion, Fig. 2 is a view showing the invention arranged as an'airdouche. Fig. 3 is a view of an air-douche having a round casing.

'In carrying out my present invention, l,

secure the motor armature or rotor 1 and the fan or ventilator blades 2 upon the same axle or 'shaft 3, the stator blades 4 of the motor being supported by one wall of the casing 5 which incloses both the motor and the fan and is provided with openings 6 in its sides to admit air. The axle 8 is journaled in the sides ofthe casing and the casing is provided with a discharge 7, preferably in its bottom. It will be noted that 'the blades 2 are secured directly upon the axle immediately adjacent the' motor and consist of a radial branch extending from the axle and anouter axial branch rojecting from the end of the radial branc along and adjacent the periphery of the motor, both branches fittings-closely to both the motor and the casing. It will also be noted .that the armature is provided with passages 8 through which air is drawn by the fan.

By arranging the motor and the fan on the same shaft within a common casing, I produce a very simple and compact structure by which a thorough circulation of a large volume of air may be easily effected.

The fan blades are disposed longitudinally of the motor shaft, and follow the contour of the casing, fitting to the same, and to the annular partition therein which carries the stationary member of the motor, as closely as possible without being in actual contact therewith. ll thus provide a large air-propelling surface within a small space and also cause the air to play around the motor and prevent heating of the same. lnasmuchas the fan draws air through the passages 8 in the armature, the armature remains cool and the motor is very durable.

My device is intended morel particularly for use as a hair-drier which may be held in the hand to direct a blast of air upon the hair being treated, this particular applica- `tion of the 'invention being illustrated in Fig. 2 in which 9 designates. the handle and 10 the discharge. In my present device, the rotating parts are brought close to the center of gravity, the rotor or armature of the motor being tted closely to the shaft, whereby the eiect of vibration land gyroscopic action is largely overcome so that the arm is not quickly tired by a constant effort to balance the apparatus.

ln Fig. 3, the casing 5 is secured within an outer casing `11 having inlet openings l2 at one side and provided with a discharge 13 alining with the discharge 7 This outer casing muies the sound caused by the rotation of the fan and the motor and also protects the parts against heating by the surrounding air.

Having thus described my invention, what ll claim and desire to secure by Letters Patent is:

1. An air-douche comprising a casing having air inlet and discharge openings, an internal annular partition on one end wall ofthe casing, a shaft iournaled in the casing concentric with said partition, an electroinotor having its rotorV secured on said shaft and its stator secured on said parti.- tion, and a plurality of fan blades secured directly upon the shaft and extendin laterally along said partition, the area o said fan blades being substantially equal to the transverse area of the space defined by the casing, the partition and the motor.

2. An air-douche comprising a casing having oppositely disposed air inlets in its end and an intermediate discharge, an internal annular partition on one end Wall of the casing, a shaft extending between the end Walls of the casing concentric with said partition, an electromotor having its rotor secured on said shaft and its stator secured on said partition', and a plurality of fan blades secured directly upon the lshaft and disposed longitudinally thereof, said blades having an area substantially equal to the transverse area of the space defined by the casing, the partition and the motor, and the edges of the blades tting closely to the 15 AUGUST SCHAEFFER.
